It happens in many cases, after installing a Linux system on a hard disk already partitioned, these "partitions" are not installed automatically when system boots. So, that leads to have to mount partition each time you want to use it, which is removed once computer off and when turned back on, we have to be reassembled and so on.

So let's see then how to make partitions on your disk are mounted automatically at startup. Note that in this article we are dealing with Linux partitions with file systems ext2, ext3, etc. The partitions that we use to save documents, movies, music, etc., as opposed to using system partition.

Suppose we have two ext3 partitions, one of which is used by another system and use it to store our data, documents, etc. So, first we are going to do is create mount points for partition that we use for storage.

The directory "/media" is that we use to create directory, which we call "disk" which will be mount point for partition in question. To do so, tipeamos console as follows:

We move to directory /media

$ cd /media

We login as root

$ su

Create directory "disk"

# mkdir disk

Following this, we ensure that owner of that directory is your user.

# chown chamberdoor -R disk

Then assign permissions:

# chmod 755 -R disk

Once completed these steps, which will prepare directory mount point, we turn to tell system where you have to set up and how each part. To do this edit the file "fstab" found in directory "/etc", as follows:

Open fstab file with your favorite editor, such as: nano, vi or gedit.

# nano /etc/fstab

And at end of this file add a line that lists all data partition mounting. That line will look like this:

device/ Mount_point/ file_system/ options/ dump-freq/ pass-num

Where "device" is name of partition is in /dev, and can be called sda1, sda2, etc. We can find out by running following command: "fdisk-l". "Mount Point" refers to directory you created earlier. "File System" just file system of the partition in question, eg: ext2, ext3, etc. "Options" refers to attributes of partition, for example "defaults". "Dump-freq" is a number, indicating to "dump" on backs up the partition, if we leave it to 0 is not taken into account. And "pass-num", which also is a number, tells the program "fsck" to look for errors in partition, if we let it to 0 is not taken into account.

Taking these data into account, add at end of file "fstab" completing course set out above. What would be something like this:

/dev/sda5 /media /disk ext3 defaults 0 0

File save changes, reboot PC, and see that once system partition is automatically mounted.

Once installed press ALT+F2 and in window that opens write playonlinux and give Run button.

When loaded (may ask you somethings download Windows fonts necessary) the first thing you should do is go to Options menu> Environment and tick box to make application appear in Gnome menu:

Then, using Install button, we will deploy on left pane of window, what type of applications you want to install (games, Office, Internet, Multimedia, etc..), Choosing right one will appear in available options:

In some cases, you need CD or DVD with application or game, in others, the search and download from Internet.

Mz Game Accelerator is an application that enables us to optimize our team for games to run better. Using a "simple click", this program is responsible for making various tasks to improve performance when we play.

The tasks of optimization of this application include intelligent optimization of RAM, and cleaning and defragmenting, assign more CPU to play, reducing processor usage for other applications, and many unnecessary Windows processes while we are playing.

This program is 100% compatible with Windows XP, 2003, Vista and 7, both in 32 and 64 bits.

His intention is to carry out development of OpenOffice.org software project as a free and independent.

Oracle, which acquired rights to OpenOffice.org as a result of acquisition of Sun Microsystems, has been invited to serve on new foundation, and donate mark of community that has grown over past ten years.

Pending that decision, has been brand LibreOffice elgida for software in future.

Several organizations support project, these include Google, Novell, Canonical and Red Hat.

From now on, OpenOffice.org community is known as "Document Foundation."

Easier Mount Tool is a small application that works as a frontend for mount command written in Python and PyGTK. It also makes use of various scripts and programs to convert between different image types.

Mp3Splt is a utility to split mp3 and ogg files indicating a beginning and an end.

It is especially useful for when we have an entire album in one mp3 file.

In this case division of issues we can do it manually, but also has option to do so automatically via CDDB or silence detector.

The application itself has three parts:

Mp3Splt: The main program for command line. Exists in Ubuntu repositories but with a much earlier version.

Libmp3splt: A library created from version 2.1 Mp3Splt.

Mp3Splt-gtk: The frontend that uses library before and that gives us a graphical perform all operations.

Some of his Features are:

Support for separate ogg and mp3 files indicating beginning and end.

Support for ID3v1 and ID3v2 for MP3 files.

Separate items using freedb.org automatically.

Automatically separates silence detecting items.

Allows you to split a file into determining a duration.

Specify folder saved.

Let's see how to install it in Ubuntu.

First of all let them know that there are packages for Maverick, Lucid and Karmic 32 and 64 bits, as well as other distributions, Mac OS X and Windows.

Packets can get from download page project , but it is important when choosing type of distribution, be installed from left to right to avoid dependency problems. So first library (libmp3splt), then CLI (Mp3Splt) and finally GUI (Mp3Splt-gtk).

Looking for plugins to Rhythmbox, I find this very nice: Desktop Art is a plug-in that shows album cover, the name of song and album name and interpret that we are listening to Rhythmbox, on desktop. In addition, if we pass mouse over it, the buttons appear to advance or rewind song list, and button play/pause, giving us ability to control the audio player from desktop.

This plugin can be configured to define position of screen on which to locate position of text in image, background color, etc.. It should be noted: that supplement works, it is necessary to have a composite manager like Compiz-Fusion enabled.

Desktop Art is written in Python by Mathias Nedrebo, and using Cairo, librsvg, Glade, Pango and GTK+. The code is available via SVN. But then see how to install it.

First of all you need to install subversion, independent of the Linux distribution you are using.

In Ubuntu/Debian:

$ sudo apt-get install subversion

In Fedora:

$ su -c “yum install subversion”

This done, we can move on to installing Desktop Art

In Debian / Ubuntu:

Create folder where you will stay Rhythmbox plugins

$ mkdir -p $HOME/.gnome2/rhythmbox/plugins/

We move to directory created in previous step

$ cd $HOME/.gnome2/rhythmbox/plugins/

Download plugin directly to plugins folder

$ svn co http://nedrebo.org/svn/rhythmbox/desktop-art

In Fedora:

To have a correct operation of this complement, Fedora is necessary to resolve a dependency, which very well described in Free Range. So for this, do following:

$ su -c “yum install gnome-python2-rsvg subversion”

This done, we can continue installation. Create directory within directory Rhythmbox plugins found in user's home folder:

$ mkdir -p ~/.gnome2/rhythmbox/plugins/

We move to newly created directory:

$ cd ~/.gnome2/rhythmbox/plugins/

Download plug:

$ svn co http://nedrebo.org/svn/rhythmbox/desktop-art

Completed these steps, open or restart Rhythmbox and go to Edit -> Add. This opens configuration window Rhythmbox supplements. There Desktop Art option labeled and ready, we'll have plugin working.

When printing a web site we have problem of leaving unwanted items such as logos, images, text sections, or anything that is not our interest.

We have already discussed some solutions to that as iPrint or PrintFriendly, but today we have another alternative for Firefox users, since it is an extension. Print Edit allows us to edit and delete blocks of a website, to print only what interests us and save on paper and ink.

This extension is available for Windows and Linux,is not compatible with Mac, so they will stay with desire to try, like me.

The manager was crazy! No, this phrase was not uttered by folks at Skype, but might well have been. The company said it would offer free internet access in more than 200,000 Wi-Fi hotspots around world who are able to use Skype Access. So get ready to enjoy Internet for free during Saturday and Sunday.

To access free internet offered by Skype will need to have VoIP application installed on your computer - is for both Windows and Mac OS. From there, simply connect to any hotspot that is actually accepted by Internet access service Skype, Skype Access.

And therein lies clever bit: Vex has this support, ensuring that promotion of Skype will work in Brazil (at least that's what I hope). The full list of hotspot operators accepted here.

In announcing promotion, Skype makes it clear that free internet is valid from 00.00 on Saturday, 25 September until 23:59 on Sunday, 26 September, the GMT. Doing a quick conversion, ( official time GMT).

For users of Gnome desktop environment, extract tracks from an audio CD is a task as simple as inserting disc into drive and open "Audio CD Extractor." But for those who like to have "one", then we will see how to extract tracks from an audio CD using Rhythmbox, default audio player for Gnome.

Here's how to rip an audio CD with Rhythmbox:

First, insert audio CD in question in reader of CDs or DVDs of our team.

Automatically, the system prompts you to choose an application to run with CD. We chose "Open Rhythmbox.

Once opened Rhythmbox in left pane, under "Devices", we right-click on name of audio CD and choose option "Extract to music library"

Once this starts extraction process, whose progress can be seen in bottom right of status bar of Rhythmbox.

We hope to complete process and go! As simple as that.

Rhythmbox stores extracted files in folder "music". To open it go to menu "Places -> Music." You will notice also that Rhythmbox default rip format. Ogg. To change default format when using Rhythmbox to extract audio tracks from a CD, go to menu "Edit -> Preferences." Once there, go to tab "Music", where drop-down "format of choice", we can select format you want.

The development of next version of Firefox continues with full force and it is not uncommon to see news about browser popping up weekly. This time it is a change in user interface application that may leave some users start using confusing. The Mozilla Foundation has chosen to change display of links in status bar of all, to say basics.

For first time in history of browser - if I remember correctly, how links are displayed will change. You know when you pass mouse cursor over a clickable item and appears below page where click will take you? Well then, now that address appears in address bar itself, near directions of tabs.

Rather than explain, see in image:

Mozilla has worked well in this feature, it is nice to see it in operation. Furthermore, the area chosen for new way to display page that opens is not so lacking today in monitors - hence screen resolutions - are greater than ever.

The question is whether change will be retained in final version of Firefox 4.

Before he had spoken of Desktop Art, which integrated playback buttons and dials your desk. This time I show you something similar, but not equal. It is not same, because it adds more options and integration with desktop is better. Furthermore, another advantage is that it comes from Gloobus Preview Family

The first thing we will do is install it. To do this, open a terminal and add repository with Gloobus Cover

sudo add-apt-repository ppa:gloobus-dev/covergloobus

Then update and install with

sudo apt-get update && sudo apt-get install covergloobus

Once installed, you can access it from Applications/Accessories/CoverGloobus:

As you have noticed ... is same but not equal.

The first thing we do is set it up. For that with right button on front panel select Set Up:

If you notice, you can choose music player you're using right now, among which is:

Rhythmbox

Songbird

Exaile

Amarok

Banshee

It also enables display lyrics of music you are listening by downloading via Internet from sites that you can choose:

In addition, other option considered notable is ability to download and view guitar tabs on what you're listening:

Update

Well my friends, is that this version was updated and brought news. The most remarkable is reorganization of options, separated. It also has new options, such as being able to download lyrics at another site if not available:

As you see, is a great application, without using lots of RAM (8 Mb to be exact), adds new options to your desktop. they recommend.

everyone have a growing need: to have a tutorial on an alternative to classic cups and is available by default in Ubuntu. It certainly saves a lot of time, but more of a problem we can generate, because these drivers are outdated.

In case of HP, we can install your printer via cups. But in my case, I have a HP D1660, I had problems from outset to properly activate these drivers. Just did not want to print properly.

So, looking and looking, I learned two things:

The close relationship of HP with Linux, which has saved millions of dollars, on one hand and investing in alternatives to conventional solutions that exist for Windows, on other

The solution available for Linux as far as concerns Printer drivers, called HPLIP (HP Linux Imaging and Printing). In this way, we can access constantly updated drivers for linux and functional.

The first thing to do is download installer from set of drivers needed to enable compatibility between printer and Linux distribution available.

To do this, go to her website. Once there, select Download HPLIP, and will lead to a wizard that will request data about its Linux distribution, data from printer and model:

Select Next, and ask you to confirm data. When ready, select Next, and lower installer. Run that weighs about 20 megs:

Once downloaded, and through terminal, navigate to folder where file is downloaded. then writes:

sh hplip version?n that you have.Run

And begin to review what you downloaded. Once ready, you will be asked to choose type of installation you want to make (automatic or custom):

Once selected, you will be asked to confirm what distribution you are using:

After that, begin to check connection to Internet:

And start downloading and compiling a series of files. This process will take a lot of time not less. When you have everything ready, you will be prompted to connect USB printer to computer and turn it on. If you had put before you restart PC or remove and relocate port. I preferred to remove and put back port:

Once ready, it will open Setup Assistant, HP. He will ask you to choose how to connect your printer:

Select Next, and select printer model you're connected:

Then add the data to printer, the driver needed. Once finished, select Finish, and go .

We also have printer driver installed, a print wizard that adds a number of options, all configurable.

Among problems I have encountered driver, is that I have problems when you print in economy mode. Paper jams, for reasons still not understood. If they happened and know a solution, I appreciate that comment.

Everybody knows what is deep freeze in hasefroch right? It is an application that blocks your disk for anyone to intentional or unintentional damage to your files and folders. So if someone accidentally deletes a folder that you did not want to delete this folder with its contents 'reappear' after restart pc.

For linux we had ever seen Lethe application but never really knew if it was difficult or easy to use but today I want to submit the application Ofris which is very easy to use.

To install it on Ubuntu just have to copy following lines into a console:

sudo add-apt-repository ppa:tldm217/tahutek.net

sudo apt-get update

sudo apt-get install ofris-en

And to run only write in a console:

ofris-en

Once run will see that using it is very easy in first window tells them what they want "freezer" or block, user may be they are using, another user or all users. It also gives them option to unlock all or view current status of locks.

After choosing appropriate option only need to enter password and go. Tests can be done by deleting files or creating new ones and you will see that when you restart any of these changes are permanent. It is a special application to libraries in universities, cafes and even for your PC if there are many who use it.

If you recently purchased N900 should have discovered that most programs for Twitter available for download do not work, the fault of Twitter itself, which now only accepts signed authorization on OAuth. To resolve this problem, arises Khweeteur, a Twitter client for maemo that works seamlessly with OAuth.

The idea is Khweeteur be as simple as possible, so he has few pictures, showing DMs along with Mentions. In beginning should not be hard to confuse, but appears to be a good option until Meego is finally working with N900 ...

Information about downloading and installing Khweeteur can be found at Program site.

Not long ago it was announced that Adobe no longer continue with development of Flash Player for Linux. But a few days ago launched a preview of Flash Player 10.2 for most common platforms like Windows, Linux, Mac

They themselves say it is not final version but it is stable and usable. Besides being a faster version than previous 10.1.

To install Flash in Ubuntu follow a few steps, typing following at console:

If one of important news of release of Fedora 14 Alpha, had been beginning to useUpstart instead of systemd as session manager, today we finally heard that Fedora 14 will not.

One of great benefits of systemdir to launch system, was possibility of offering a faster boot.

The Fedora Engineering Steering Committee (FESCO), in a discussion through IRC, took decision not to include it, due to problems encountered during recent test day systemd.

The main driver of systemdir, Lennart Poettering, who did not participate in discussion, it was not too pleased with decision, inter alia, because it has apparently already been solved many of mistakes that were discovered during test day.

Although systemdir not be included in final version of Fedora 14 will be released in November, is expected to continue qualifying for incorporating possible errors in Fedora 15.

Anyway, even if not by default in Fedora 14, systemdir still available to install from repositories.

This was possible in early development of Fedora 14, when it was new and Upstart systemd still used by default.

Chromium is open source project created by Google and community participation (within scope of Google Code) to substantiate basis for design and development of Chrome browser (along with its Chrome Frame).

In Fedora 13, default browser is Firefox, so for Chromium is available to install.

Precompiled rpm repositories exist with version of Chrome with whom we can.
